Eigenvalues
of the generalized eigen problem where the mass and stiffness matrices
are symmetric with real coefficients. The eigenvalues are determined by
the Jacobi method.

The
first eigenvalue and eigenvector via the inverse iteration method.

Eigenvalues
of the generalized eigen problem where the mass and stiffness matrices
are symmetric with real coefficients. The eigenvalues are determined by
calculating the roots of the determinant polynomial. The upper limit is
fourth order.
